ARM: imx5: add missing put_device() call in imx_suspend_alloc_ocram()

if of_find_device_by_node() succeed, imx_suspend_alloc_ocram() doesn't
have a corresponding put_device(). Thus add a jump target to fix the
exception handling for this function implementation.

Fixes: 1579c7b9fe01 ("ARM: imx53: Set DDR pins to high impedance when in suspend to RAM.")
